1. The Food and Drug Administration did not submit any records. Enter the homepage of Food and Drug Administration, and there is a column about cosmetics. You can check the brand name of lipstick and see if there is any record. If not, of course not. In addition, you can also inquire about drugs, skin care products, health care products and other products here. Note that the more expensive the lipstick, the more it must be filed. You must check the unknown brand.

2. The packaging material is poor. In fact, the cost of lipstick tube accounts for more than the formula, and the price difference between good packaging materials and poor packaging materials can reach 6-7 times. A lipstick mold costs tens of thousands of pieces, and many brands don't have this cost investment. Lipstick with inferior packaging materials is either difficult to pull out the lid or the lipstick paste is crooked.

3. The smell is pungent. Lipstick usually smells good. Even if the taste is unique or even strange, it will never be pungent, which is the inferior taste of essence. Generally, the bigger the brand of lipstick, the taste is also its symbol. Experienced girls can sniff out whether this big-name lipstick is genuine or not from the smell.

Extended data:

Distinguish whether it is inferior lipstick, and the product description is incomplete. Good quality lipstick, even if it is simply installed, the production license, ingredients, trademarks and so on are clearly visible. The lipstick you bought can't be used without writing, knowing the ingredients and trademarks, and without a production license.

Inferior lipstick, caking is not easy to apply. Good lipstick will not dry evenly, will not agglomerate, will not have the grainy feeling of impurities, and will not cause discomfort or irritation when applied to lips. Especially the big-name lipstick, the smoothness of the mouth is the same as that of chocolate on the mouth, which is very easy to use. Inferior lipstick will be astringent or dry, and it will have a strange taste.

Tar pigment is the most harmful of inferior lipstick in cosmetics. Tar pigments such as red 202 used in lipstick are at risk of contact dermatitis and skin cancer. Because the lips have almost no stratum corneum, the transdermal absorption rate is extremely high. If you swallow the fallen lipstick, it will become oral intake, so pay attention to the dangers of chemicals used in lipstick.

Inferior lipstick products, mixed with polymer as a covering agent, wrap lipstick on the lips. This means that lipstick is attached to the lips for a long time, and the danger is greatly increased. After using indelible lipstick, symptoms such as abnormal dryness and roughness of lips appear. Although it is a convenient product to save makeup time, it should be avoided as far as possible from the point of view of preventing transdermal toxicity.
